Summary: A series of SiC/Al composites with different contents of 3-dimensional graphene networks (3DGN) were prepared using mechanical alloying and spark plasma sintering. The effects of 3DGN on the microstructure, mechanical properties, and corrosion behaviors of SiC-3DGN/Al composites were investigated. The results showed that 3DGN substantially enhanced the synergistic strength-toughness of SiC/Al composites by improving the interface cohesion and increasing hardness, density, ductility, and corrosion resistance in NaCl solution.

Summary: Al/SiC composites fabricated by plasma activated sintering (PAS) can achieve high relative density above 99% at 530°C. Plasma activation can remove oxide impurities on Al and SiC surface, which leads to the formation of an Al-Si diffusion layer and Si1-xC through Al and SiC reaction, resulting in the generation of Al4C3. The rapid sintering effect of PAS contributes to the high tensile strength of 256 MPa.

Summary: The study prepared 50 vol% SiC/Al composites with different SiC particle size and Al alloy composition using Spark Plasma Sintering. The thermal properties, microstructures, and interface reaction products of the composites were investigated. The optimization of composite components and sintering process parameters were conducted. It was found that SiC particle size and sintering process parameters were crucial for obtaining high thermal-mechanical properties of the composites. The best physical properties were achieved in the 16 μm SiC/6061Al composites sintered at 50 MPa, 8 min, and 520°C, with bending strength of 649 MPa, thermal conductivity of 189 W/(m·K), and coefficient of thermal expansion of 7.9×10-6 K-1 at 50-100°C. XRD and SEM analysis revealed the absence of hazardous reaction product Al4C3 at the interface and the growth of MgAl2O4 and Mg2Si together at the interface.

Summary: This work aimed to develop an aluminum alloy brake disc with a wear-resistant SiC particle reinforced aluminum matrix composites (SiC/Al) on its surface. Different joining technologies, such as brazing and shrink fitting, were used to connect SiC/Al to the aluminum alloy. A functional graded structure was created by gradually increasing the SiC particle content in the aluminum matrix composites. Tribological tests demonstrated that the aluminum alloy brake disc with SiC/Al brazed on its surface offers promising technical opportunities.

Summary: SiCf/SiC composites fabricated through a two-step pyrolysis process and LSI process exhibit increased density, reduced porosity, and higher flexural strength compared to those fabricated through a one-step pyrolysis process. Among specimens processed with the same two-step pyrolysis, those subjected to LSI at 1500 degrees Celsius show significantly higher flexural strength than those at 1450 or 1550 degrees. Additionally, mechanical properties of SiCf/SiC specimens processed at 1500 degrees Celsius are superior to those at 1550 degrees Celsius despite similar porosity and density due to the rapid degradation of Tyranno-S grade SiC fibers at higher LSI process temperatures.

Summary: Understanding the statistical properties of mechanical properties in non-irradiated and neutron-irradiated SiC/SiC composites is crucial for component design. This study evaluated the damage accumulation behavior of composites, focusing on fracture parameters such as proportional limit stress and acoustic emission onset stress. The study used underwater acoustic emission technique and conducted four-point flexural tests to evaluate the post-irradiation strength of two types of SiC/SiC composites. The results showed that the reliability of composites is crucial for expanding design margin and utilizing a probabilistic design approach.

Summary: Diamond/aluminum composites were fabricated using gas pressure infiltration method with different raw materials. The effect of interfacial phase type and size on thermal conductivity was investigated, as well as the evolution of microstructure and properties under temperature shock environment. The results showed that the introduction of W and WC coatings could inhibit the formation of interfacial phase Al4C3. However, the generation of amorphous carbon in WC-coated diamond/aluminum composite led to a weak interface bonding and a decrease in thermal conductivity. The W-coated diamond/aluminum composite exhibited the optimal thermal properties after 1000 cycles of temperature shock treatment, with improved performance stability and high thermal conductivity.

Summary: Based on the microscopic process of particle erosion in solid rocket motor combustion chamber walls, this study analyzes the erosion mechanism of aluminum droplets when impacting solid walls vertically. The impact force of high-temperature molten metal droplets is measured using a pneumatic droplet generation method and piezoelectric force measurement technology. The study systematically investigates the impact force of aluminum droplets with different diameters and velocities. Numerical simulations and experimental results are combined to explore the impact force generation mechanism and the influence of various parameters during the rebound process. The research work enhances the understanding of insulation material mechanisms in solid rocket motor combustion chambers and expands knowledge in engine structure design.

Summary: In this experimental research, Al 8011-SiC composites were fabricated by the stir casting method with different stirring time periods and stirring speeds. The results showed that the highest hardness, yield strength, and tensile strength were obtained under the maximum stirring conditions, along with the highest elongation. The toughness of the composites remained unchanged for all stirring speeds and stirring times. The mechanical properties, except the toughness, gradually increased with the rise of stirring speed and time.
